/* The Wheel — v16 beta launch site
   Locked Black Fig / Verdigris palette (website/final-brand-site/README.md).
   Rulebook carried from v15/brand handoff:
   - Verdigris marks permission, proof, and action. Never decoration.
   - One black-fig authority moment per page.
   - Radius ≤ 16px. No shadows, no gradients, no side-stripe accents.
   - Fonts self-hosted: a font CDN is a tracking surface with better typography.
